1 Claim. 1

This invention relates to hub lining devices for locomotives, and more particularly to a liner device adapted to be installed on a driving wheel or other wheel of a locomotive between the wheel hub and the journal box to take up lateral wear.

A main object of the invention is to provide a novel and improved hub lining device for locomotive wheels said device being very simple in construction, easy to install and not being subject to accidental loosening.

A further object of the invention is to provide an improved hub lining device of two part interlocking construction which can be mounted on the locomotive journal with a minimum of dismantlement of parts of the locomotive which is inexpensive to fabricate, and wherein the two parts thereof are substantially identical, whereby manufacture of the device is greatly simplified.

Further objects and advantages of the invention will become apparent from the following dcscription and claims, and from the accompanying drawings, wherein:

Figure 1 is a face view of one side of a hub liner device constructed in accordance with the present invention, shown in assembled position.

Figure 2 is a face view of the opposite side of the hub liner device of Figure 1.

Figure 3 is an enlarged cross-sectional detail view taken on line 33 of Figure 1.

Figure 4 is a, perspective view of one of the body elements of the hub liner device of Figure 1.

Figure 5 is a cross-sectional view taken on line 5--5 of Figure 1.

Figure 6 is a cross-sectional view taken on line 6-6 of Figure 2.

Referring to the drawings, I I designates a first body member, which may comprise a single brass casting, said body member having a disc portion I2 formed with a rectangular notch I3 having a rear wall I l located in a diametral plane of the disc portion. Aligned with and opposite notch I3, is a lug portion I5 carried on the face of disc portion I2 and of equal thickness therewith, the outer arcuate edge I6 of said lug portion being flush with the adjacent arcuate peripheral edge of the disc portion. The inner edge ll of the lug portion is straight and is flush with the rear wall I4 of notch I3. Formed in the edge I! and rear wall It at the center of the disc portion I2 is a semi-cylindrical axial seat I8 adapted to fit the locomotive wheel shaft. The side walls of slot I3 are bevelled outwardly at a 45 degree angle with respect to the plane of disc portion I2, as shown at I9, I9. The side edges of the lug portion I5 are also flared at a 45 degree angle to define a dovetail cross-section as shown at 2|], 2|]. Disc portion I2 is formed with four openings shown at 2|.

Designated at 22 is a body member substantially identical with body member I I and having a dovetailed lug portion I5, except that the openings in the disc portion thereof, are countersunk at 23 to form square pyramidal recesses. The disc openings of member 22 are spaced so as to register with the disc openings ZI of member !I when the members II and 22 are interlocked, as will be presently described.

To assemble the liner device on a wheel shaft, one of the body members is seated on the shaft and the other body member is fitted to the first body member so that the dovetailed lug portions mutually interlock with the dovetailed notch walls I9. The other body member is; then slid toward the first body member so that the wheel shaft is embraced by both semi-cylindrical seat portions It of the body members and the diametral inner edge portions I4 and I! of the respective body members are in abutment. The openings 2I of body member II are then in registry with the countersunk face openings of the body member 22. Bolts or rivets are then passed through the aligned openings to secure the body members rigidly together. The heads of the bolts or rivets are pyramidally contoured at their under surfaces so as to non-rotatively fit the countersink 23. Where rivets are employed, the ends of the rivets are upset in a conventional manner against the outer surface of body member II.

The lug portions I5 and I5 may be welded or otherwise permanently secured to the disc portions instead of being cast integrally therewith.

While a specific embodiment of a hub lining device for locomotives has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore it is intended that no limitations be placed on the invention other than as defined by the scope of the appended claim.

What is claimed is:

A locomotive hub liner comprising a pair of overlying circular disc elements, each having a rectangular notch opening on one side thereof, spaced apart bevelled side edges on each of said notches parallel with respect to each other on a radius of the respective disc, and a rectangular lug element on each of said discs extending diametrically opposite from the respective notches, the side edges of said lug elements being bevelled 3 for dove-tailed sliding engagement with the side edges of the notches on the opposite disc element, the diametral surface defined by the notch rear wall and lug element on each disc element being formed with a semi-cylindrical axial seat for receiving a wheel axle, each of said disc elements having circumferentially spaced apart registering face openings adjacent the respective notches and lugs to receive fastening means therethrough for securing said disc elements to-' gether in interengaged relation about a wheel axle.
